Description

Lug that sprays paint covers frock

Technical Field

The utility model relates to the technical field of paint spraying of aircraft pipe fittings, in particular to a paint spraying lug covering tool.

Background

The requirement that the tabs on the pipe be lined with no paint is met, although the design requires that the parts of the aircraft pipe be painted. This area is masked.

Cut beautiful line sticky tape or purchase the sticky tape of assigned size, need tweezers cooperation to use because space restriction and cover the region of not spraying paint, the operation is more loaded down with trivial details, need the tangent circle to block up bush and pinhole. The non-painted area around the pin hole cannot exceed a tolerance of 0.1 in. After the paint is dried, the adhesive tape at the covered part needs to be removed to prevent generation of excess materials, and the paint is possibly brought down to cause rework.

SUMMERY OF THE UTILITY MODEL

The application provides a auricle that sprays paint covers frock, and the auricle neck bush that its aim at solved current aircraft pipe fitting covers the painting process comparatively loaded down with trivial details, and the use of sticky tape easily produces the problem of doing over again.

In order to achieve the technical purpose, the following technical scheme is adopted in the application:

the utility model provides a lug that sprays paint covers frock, includes: the bolt rod comprises a raised screw head and a screw with an external thread; the covering gasket is of a cylindrical structure with a through hole in the center, a covering hole is formed in the bottom of the covering gasket upwards, and the covering hole is communicated with the through hole; the bolt blocking cap comprises a convex cap head and a rod sleeve extending out, wherein an internal thread is arranged in the rod sleeve and is matched with an external thread on the screw rod; the covering gasket covers the outer side of a non-painting area, and the bolt rod penetrates through the through hole to be screwed with the bolt plugging cap.

Preferably, the inner wall of the through hole is provided with a second internal thread, and the second internal thread is matched with the external thread of the screw rod.

Preferably, the length of the screw is not less than the length of the rod sleeve.

Preferably, the diameter of the rod sleeve matches the diameter of the unpainted region.

Due to the adoption of the technical scheme, the paint spraying lug covering tool is simple in structure and can effectively cover the inner bushing; can be repeatedly used for many times, has low cost and can not generate the condition of excess due to incomplete removal.

Detailed Description

The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.

Fig. 1 shows an aircraft pipe 1 to be painted. As shown in fig. 1, the inner liner 2 inside the tab 11 is an area that does not require painting. One end 21 of the inner sleeve projects from the right side of the tab, while the other end 22 of the inner sleeve does not project.

Referring to fig. 2, the painting tab covering tool of the present application includes three components, a bolt shank 3, a covering washer 4, and a bolt plugging cap 5.

The bolt shank 3 comprises a raised screw head 31 and an externally threaded screw 32. The covering gasket 4 is a cylinder structure with a through hole 41 at the center, and is slightly flat, the bottom of the covering gasket 4 is upwards provided with a covering hole 42, and the covering hole 42 is communicated with the through hole 41. The bolt plugging cap 5 comprises a convex cap head 51 and an extended rod sleeve 52. An internal thread is provided in the rod sleeve 52, which internal thread matches with an external thread on the screw 32. Preferably, the length of the screw 32 is not less than the length of the rod sleeve 52, so as to be suitable for lugs 11 with different spacing. For further stability of the combination, the inner wall of the through hole 41 is provided with a second internal thread matching the external thread of the screw 32. The diameter of the rod sleeve 52 is matched with the diameter of the non-painted area, namely the other end of the inner bushing, and is directly pressed against the outer side of the lug.

As shown in fig. 2 and 3, the covering washer 4 covers the non-painted area, i.e., the outer side of the inner bushing, and the bolt shank 3 is screwed to the bolt cap 5 through the through hole 41. The bolt shank 3 and the bolt blanking cap 5 are suitably tightened against the covering gasket 4. After the installation is finished, the tools are disassembled in sequence after the paint is dried.

The paint spraying lug covering tool is simple in structure and can effectively shield the inner bushing; can be repeatedly used for many times, has low cost and can not generate the condition of redundant substances due to incomplete removal. The utility model provides a auricle that sprays paint covers frock can adopt the simple disposable frock of input of PVC material processing to use repeatedly.

The above-described embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. All equivalent changes and modifications of the utility model that may occur to those skilled in the art are intended to be covered by the appended claims.
